Play HTTP Live Streaming

Example Brief

This example demonstrates how to play Internet radio in real-time over HTTP Live Streaming (HLS) in the ESP-ADF.

The pipeline is as follows:

[living_server] ---> http_stream ---> aac_decoder ---> i2s_stream ---> [codec_chip]

Environment Setup

Hardware Required

This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.

Build and Flash

Default IDF Branch

This example supports IDF release/v3.3 and later branches. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.

Configuration

The default board for this example is ESP32-Lyrat V4.3. If you need to run this example on other development boards, select the board in menuconfig, such as ESP32-Lyrat-Mini V1.1. If you select CONFIG_ESP32_C3_LYRA_V2_BOARD, you need to apply idf_v4.4_i2s_c3_pdm_tx.patch in the $ADF_PATH/esp-idf directory.

menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1

Run menuconfig > Example Configuration to first configure the Wi-Fi connection information and fill in the Wi-Fi SSID and Wi-Fi Password.

menuconfig > Example Configuration > (myssid) WiFi SSID > (myssid) WiFi Password

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):

idf.py -p PORT flash monitor

To exit the serial monitor, type Ctrl-].

See ESP-IDF Programming Guide for full steps to configure and build an ESP-IDF project.

How to Use the Example

Example Functionality

  • After the example starts running, it connects to the Wi-Fi hotspot actively. If the connection succeeds, the example fetches the built-in live streaming audio from the Dragonfly FM Internet Radio for playback. The log is as follows:
